Abstract

A device for inducing anaesthesia, analgesia and/or sedation is described which comprises a container holding an inert gas-containing liquid preparation, and means for the controlled administration of the preparation to a patient.

Claims

1. Device for carrying out controlled anaesthesia, wherein the intravenous supply of an infusion solution containing a lipophilic inert gas is adjusted as a function of the inert gas concentration in the air exhaled by a patient, comprising a container for the infusion solution holding said solution which contains said lipophilic inert gas and a metering means for controlling the infusion rate.

2. Device according to claim 1 wherein a patient'"'"'s experimental data are additionally recorded, allowing a conclusion to be drawn about the patient'"'"'s depth of anaesthesia.

3. Device for controlled anaesthesia, analgesia and/or sedation, characterized in that the device comprises a container holding a liquid preparation which contains a lipophilic inert gas in an amount effective as an anaesthetic, analgesic or sedative, and means for the controlled administration of the preparation to a patient,

wherein provision is made for a storage container for a liquid preparation which can take up an inert gas in dissolved form, a gas container for the inert gas, and a metering means for feeding inert gas into the mixer, in which the liquid preparation is mixed with the inert gas.

4. Device for inducing sedation, characterized in that the device comprises

(a) a facility which provides a liquid preparation containing a lipophilic gas in an amount active as a sedative,

(b) a means of measuring data, which records a patient'"'"'s data, said data allowing a conclusion to be drawn about the patient'"'"'s condition, and

(c) a control means which controls the administration of the emulsion from the facility to the patient as a function of the measured data.
